Web2 days ago · If I call the repository methods explicitly in the code to save/ get data, it works fine but when the application is running, many functionalities work fine but at some or the other place a JPA repository method throws the "javax.crypto.IllegalBlockSizeException: Input length must be multiple of 16" exception and it is not able to decrypt. WebCrypto.Util.number.long_to_bytes(n, blocksize=0) Convert a positive integer to a byte string using big endian encoding. If blocksize is absent or zero, the byte string will be of minimal length. Otherwise, the length of the byte string is guaranteed to be a multiple of blocksize. If necessary, zeroes ( \x00) are added at the left. Note

Web加密原理： 使用sm2生成一对公钥和私钥。然后将公钥发送给前端，私钥自己在后端进行保存 （本次示例是将私钥保存在redis中，因为redis是使用键值对进行保存数据的，所以还需要生成一个uuid进行保存和获取密钥数据。 前端使用公钥进行加密，然后将加密的数据发送给后端，后端使用对应的私钥 ... WebJun 10, 2024 · For the key length, you should use at least 2048 (NSA recommends 3072 or larger ref ). Note that RSA can only encrypt data up to the key length (including padding). So, with a key of 2048 bits, you cannot encrypt a blob of 4096 bits. You'll need to split it into 2 blobs and encrypt them separately. C#

So preferably the entropy of the 256 bit key should be condensed into 32 bytes. What you are talking about is probably the hexadecimal representation of those 32 bytes. If the key is too large it may affect performance and efficiency of the HMAC function.
